[Freeswitch-users] SIP 100 response and media

[Boris Kovalenko]

Hello!

     This thread again. There are two logs. First between Cisco<->Cisco 
call and second between Cisco<->FreeSwitch. Cisco<->Cisco works fine. As 
I can see the difference is that
Cisco has a=rtpmap:8 PCMA/8000 and FreeSwitch not. May be this is a 
problem? Is this field mandatory?
